• https://docs.openshift.com/container-platform/4.15/observability/monitoring/monitoring-overview.html#openshift-monitoring-common-terms_monitoring-overview
• https://docs.openshift.com/container-platform/4.15/observability/monitoring/configuring-the-monitoring-stack.html#configurable-monitoring-components_configuring-the-monitoring-stack (NOTE: Add Metrics Server to the table)
• https://docs.openshift.com/container-platform/4.15/observability/monitoring/configuring-the-monitoring-stack.html#specifying-limits-and-resource-requests-for-monitoring-components_configuring-the-monitoring-stack (Remove from YAML sample)
• https://docs.openshift.com/container-platform/4.15/observability/monitoring/configuring-the-monitoring-stack.html#setting-audit-log-levels-for-the-prometheus-adapter_configuring-the-monitoring-stack (remove this include from the assembly)
